To be fair, TfL has committed to installing safer cycle infrastructure into this roundabout and will have built that in time for the Olympics. That still won't make the rest of the blue paint route particularly safe, let alone pleasant, though.

Yesterday, at the Olympic Transport committee in the London Assembly. So the man responsible for London's road, Leon Daniels, was wrong to say cyclists should cycle along the floating towpath because it's not going to be an option.

"Jenny Jones: I'm glad you've mentioned the Greenway because you've actually made life much much harder for cyclists to get there by closing - apparently the underpass, the canal underpass under Bow roundabout is being closed May to September which is fairly drastic isn't it when you imagine a lot of cyclists would use it and you've also closed the Greenway route from Wick Lane

Now those two things mean that cyclists are going to have to use the Bow Roundabout which will not be at its best - it certainly won't be to the level of safety that we've all discussed. You're actually forcing cyclists off of Greenways onto dangerous roundabouts.

I don't think matters are quite as apocalyptic as Jenny Jones makes out. You'll still be able to get to the Olympic park from the south but I imagine you'll have to detour and cross the six lane motorway also known as Stratford High Street. But Jenny Jones does have a point.

I'm glad that Transport for London is implementing a new scheme to make it safer for people to cycle east to west across Bow roundabout. But I think it's tragic that even the one tiny piece of cycling infrastructure that was put in place for the Olympics is actually not for the Olympics at all. It's only going to be useful after the event. As usual, if you want to cycle to the Olympics, you can expect to take a detour, dismount from your bike, cross the motorway, may be you'll be able to get back on your bike again after that.

But I find it profoundly depressing how we're completely failing to build cycling into this massive scheme. Here was a one-off chance to get cycling right. Brand new urban environment, real opportunity to build cycling as a sensible, safe urban mobility option for everyone. And what's happened? A bit of a tow path, a bit of a greenway, a bit of retro-fitted infrastructure on a killer roundabout but only after thousands of people protested.

I managed to buy tickets for the Olympics. I'm quite excited. And I'd like to cycle there. But I'm not going to bother cycling. It seems like too much hassle, frankly. I'll take the tube. Or I might drive instead. Because the Mayor of London is letting people make London a city for driving in. The thing is, the Mayor also wants to make London less congested. He knows there are more and more people and they can't all drive their cars all the places they want to without the whole thing coming to a halt. At some point he needs to lead his cycling revolution from the front. And that means telling people in the various Olympic authorities that they're not up to scratch just as much as it means he can't get away with just slapping blue paint around the place.
